Trailer King Tires

A trailer that’s been sitting through the off-season deserves a quick check before the next haul. Trailer King tires are a practical fit for Robertson Tire customers who need ST replacement tires for RVs, boats, cargo trailers, and utility rigs without overcomplicating the decision.

If your setup carries heavier loads or sees more highway miles, start with Trailer King Ultra STR. Its all-steel construction is a strong step up for demanding towing, while Trailer King RST is the everyday radial option for common replacement needs. The right choice usually comes down to load range, wheel rating, and cold PSI, not just the size on the old sidewall.

Robertson Tire can help verify your trailer specs in person so you can match the tire to the job, whether you’re headed to the lake, the jobsite, or a weekend getaway. Bring your trailer information by for a fitment review, or start with Shop Tires to compare options.
